Technical Analysis
CVE-2026-14991 is a critical buffer overflow vulnerability (CWE-787) in IBM DataPower Gateway versions 10.5.0.0 to 10.5.0.22, 10.6.0.0 to 10.6.0.10, 10.6.1 to 10.6.6, and 11.0.0.0 to 11.0.0.2. The vulnerability arises from improper bounds checking that enables a local user to perform an out-of-bounds write, potentially leading to arbitrary code execution on the system.
Potential Impact
Successful exploitation of this vulnerability could allow a local attacker to execute arbitrary code with the privileges of the affected application, potentially leading to full system compromise. The CVSS v3.1 base score is 9.8, indicating critical severity with high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until a fix is available, restrict local user access to trusted personnel only and monitor for suspicious activity related to this vulnerability.
